Abstract The revolution of millimeter‐wave (mmWave) technologies is prompting a need for absorption‐dominant EMI shielding materials. While conventional materials struggle in the mmWave spectrum due to their reflective nature, this study introduces novel film with ultralow reflection (<0.05 dB or 1.5%), ultrahigh absorption (>70 98.5%), and superior 99.99999%) across triple frequency bands thickness 400 µm. By integrating magnetic composite layer (MCL), conductive patterned grid (CPG), double‐walled carbon nanotube (DWCNTF), specific resonant frequencies electromagnetic waves are transmitted into minimized reflection, trapped dissipated between CPG DWCNTF. design factors frequencies, such as geometry MCL refractive index, systematically investigated based on wave propagation theories. This innovative approach presents promising solution effective materials, implications mobile communication, radar systems, wireless gigabit communication.

Abstract Slow rebound polyurethane foam (SPUF) has developed rapidly because of its excellent performance in sound insulation, energy absorption, and tactile sensation. However, the friction‐induced electrostatic charge accumulation occurs easily due to high resistivity. In this paper, dimethyl octadecyl hydroxy ethyl ammonium nitrate (SN) intercalated reduced graphene oxide (SN‐RGO) were prepared as conductive agent. The antistatic slow (ASR‐PUF) was with SN‐RGO/carbon black system silicone‐modified polyethylene glycol (Si‐APEG) low temperature resistant structures SN‐RGO investigated by Fourier transform infrared spectra (FT‐IR), wide‐angle X‐ray diffraction (WAXD), scanning electron microscope (SEM), respectively. effects on structures, mechanical properties, low‐temperature resistance, property ASR‐PUF studied.
